What are PDO and COG Threads?
PDO (Polydioxanone) and COG threads represent an innovative, non-invasive method for lifting and tightening the face and body. They are absorbable medical sutures placed within the dermis to create an internal support mesh that remodels the skin’s contour and stimulates natural collagen production. This technique, also known as “non-surgical lifting,” delivers impressive results in lifting and rejuvenating the face without surgery, incisions, or prolonged recovery time.
There are two main types of threads: simple PDO threads, which provide general reinforcement and tightening, and COG threads, which have barbs (hooks) that offer mechanical lifting comparable to a mini facelift. The threads are fully biocompatible and are absorbed by the body within 6–8 months, leaving behind a strong collagen network that supports the tissues.
The treatment is indicated for both women and men experiencing mild to moderate skin laxity, especially in areas such as the facial oval, cheeks, lower jawline, neck, and even eyebrows. It can also be applied to the body—for example, the inner arms, abdomen, buttocks, or thighs—with the goal of tightening and toning.
How is the procedure performed?
The session begins with a detailed assessment of the patient’s needs and the anatomy of the face or the treatment area. The doctor designs the treatment plan, deciding the type and arrangement of threads depending on the desired result. The area is thoroughly cleansed and disinfected, and local anesthesia is applied (either injectable lidocaine or topical cream) to ensure maximum comfort.
The threads are inserted into the skin using special fine needles or cannulas. Depending on their type, the threads either remain fixed (PDO) or are gently pulled (COG) to provide mechanical lifting. The insertion is minimally traumatic and does not require incisions. After placement, the doctor adjusts and checks the uniformity of the result and removes the needles.
The session lasts between 30 and 60 minutes, depending on the number and type of threads used. Mild bruising or swelling may appear immediately afterward, which usually subsides within 3–5 days. Patients can return to their daily activities immediately but should avoid intense exercise, exaggerated facial movements, and pressure on the treated area for 4–5 days.
The result is partially immediate (due to mechanical lifting) and gradually improves over 2–3 months as collagen production and tissue tightening are enhanced. The effects last approximately 12–18 months, depending on age, skin quality, and lifestyle habits.
What are the advantages of thread treatment?
The use of PDO and COG threads offers an excellent alternative to surgical lifting, without the complications, recovery time, or cost associated with invasive procedures. It is a completely safe treatment when performed by a specialized physician, providing immediate and natural-looking results. One of the most important benefits is the stimulation of natural collagen production, which improves overall skin quality and texture even after the threads have been absorbed.
Moreover, the method is highly customizable: it can be tailored to each individual’s needs, combined with other treatments (such as mesotherapy, PRP, hyaluronic acid, or Botox), and provides gradual, subtle yet impressive rejuvenation. The treatment is ideal for people who show signs of sagging but are not ready or do not wish to undergo surgery, as well as those seeking maintenance or prevention of aging.
The result looks completely natural, without unnatural tension or distortion. The face retains its natural expression while the tissue structure and support are enhanced. This technique can even be applied to younger patients with early signs of laxity, helping prevent or delay the need for more invasive solutions in the future.
